sfepy.discrete.fem.geometry_element module¶
GeometryElement describes the geometric entities of a finite element mesh.
Notes¶
- geometry_data: surface facets are assumed to be of the same kind for each geometry element - wedges or pyramides are not supported.
- the orientation is a tuple: (root1, vertices of direction vectors, swap from, swap to, root2, ...)

create_geometry_elements
(names=None)[source]¶ Utility function to create GeometryElement instances.
Parameters: names : str, optional
The names of the entity, one of the keys in geometry_data dictionary. If None, all keys of geometry_data are used.
Returns: gels : dict
The dictionary of geometry elements with names as keys.
